I've been trying to find a projector equipped with RS232 for my main media roomto no avail. Most of the projectors I've found so far are equipped with a service port.It seems that the industry is moving away from RS232 and opting to implement RJ45. Shouldn't we move in that direction as well?

Your Thoughts.

Again, most service ports can be used for that purpose but not all.My point is, should we drop RS232 altogether and move towards RJ45 ?

Hi John,I think there are many high(er)-end devices that use RS232, a lot of them have that port specifically with systems integration in mind. Among those are quite a few excellent amplifiers, for example, which have great sound but may be five or more years old. It would be a shame to stop supporting these.It is, of course, nice to know that LinuxMCE is moving along with newer technologies (as Posde already wrote above)!My 2 eurocents,Mark

Most of the so called service ports can be used to control the devices.

And we already are able to control stuff using TCP/IP

posde,

Hmmm... for the forseable future there will many devices that will continue to support rs232 and of course many 'legacy' devices too. If there is a specific protocol/physical interface that you feel is needed then suggest it...or even better just go and implement it yourself.

We need to add support for new protocols/interfaces...not remove widely used ones!

For clarification RS232 is a communication protocol. RJ45 is a cable connector (used for ethernet cat5 cabling for example) and has nothing itself to do with the communications protocols. I have a UPS which has an RJ45 port with an adaptor to 9pin d-sub to connect to my pcs serial port which uses the RS232 protocol. RS232 and RJ45 cannot be compared.

We have support for just about every single _standard interconnect_ that has some sort of published standard. Just because your projector is using a proprietary connector without published protocol specifications is not our problem. Get something with a published control protocol.

Thom,

I am aware of that. However, wouldn't it be great if there were a unified protocol under which most or all devices would be covered.I know, Wishful thinking.

If you can't find a projector with RS232... you're not looking too hard... Most projectors I've seen installed in presentation rooms are controlled over RS232. Also, the projector running above my head right now is RS232.

No, RS232 support should not be "dropped" - that would be very dumb... why would we take a step backwards? we're trying to support MORE hardware not less... Lots of people are using RS232 successfully - including me. Lots of devices manufactured today can be controlled by RS232... just because the projector you want isn't, doesn't mean that the receivers, televisions, cable boxes, and other special devices that other people have don't use it... you need to look at the bigger picture before you suggest dropping a feature that isn't useful to you.

I am looking at the bigger picture. Look around, most New Mobos come without these ports, YES, I know with things like the GC100 we can still interface with our RS232 equipped devices. Also I am not suggesting that we DROP RS232. That would be DUMD indeed. I'm just saying that RS232 is being Phased out.Should we follow that trend as well ?

John.

P.S. Which Projector are you running ?

These terms are interchangeable these days..... RJ45/Ethernet............. RS232/Com Port............

That was the point.
